Front Brake Rotor Replacement

Front Brake Rotor Replacement (LSA)

Special Tools

* J-41013 - Rotor Resurfacing Kit

* J-42450-A - Wheel Hub Resurfacing Kit

Removal Procedure

Warning: Refer to Brake Dust Warning Brake Dust Warning.


1. Inspect the fluid level in the brake master cylinder reservoir.

2. If the brake fluid level is midway between the maximum full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.

3. If the brake fluid level is higher than midway between the maximum full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.

4. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.

5. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (w RT2) Tire and Wheel Removal and Installation (w RT2)Tire and Wheel Removal and Installation (w/o RT2) Tire and Wheel Removal and Installation (w/o RT2).

6. If reinstalling the brake rotor, match mark the brake rotor relationship to the wheel hub.





Note: The brake caliper bolts must be replaced any time they are removed. Do not reuse the brake caliper bolts.

7. Remove and discard the brake caliper bolts (1).

Caution:
Support the brake caliper with heavy mechanic wire, or equivalent, whenever it is separated from its mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak.

8. Remove the brake caliper and support with heavy mechanics wire or equivalent.




9. Remove the brake rotor bolt (1).

10. Remove the brake rotor.

Installation Procedure

Note: Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.

1. Using the J-42450-A - Wheel Hub Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.

2. Using the J-41013 - Rotor Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor.

3. Install the brake rotor.
Align the match mark made prior to the brake rotor removal, if necessary.





Caution: Refer to Fastener Caution Fastener Caution.

4. Install the brake rotor screw (1) and tighten to 10 Nm (89 lb in).

5. Install the brake caliper.





Note: The brake caliper bolts must be replaced any time they are removed.

6. Install new brake caliper bolts (1) and tighten to 40 Nm (30 lb ft) + 90 degrees.

7. Install the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation (w RT2) Tire and Wheel Removal and Installation (w RT2)Tire and Wheel Removal and Installation (w/o RT2) Tire and Wheel Removal and Installation (w/o RT2).

8. If the brake rotor was refinished or replaced, or if new brake pads were installed, burnish the brake pads and rotors. Refer to Brake Pad and Rotor Burnishing Procedures.
